Charting the landscape of the environmental exposome

open access: yesiMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push
